How to move head of bone to 0,0,0 and have the other selected bones and mesh move equally with it?
I don't think you want to move your mesh or armature in edit mode; then you will move them away from their Origin, which can cause all kinds of weird behavior. Go to 3D Viewport &gt; Object &gt; Set Origin and pick one (Origin to Geometry for instance), or use it in combination with selecting stuff, Shift + S, and the 3D Cursor to get it in the best location for you. Origins can only be moved in Object Mode. Make sure the Object Origins are the right place, and move your rigged body as a whole in Object Mode.
